Spark plug suggestions

[intergalactica]

Any suggestions which spark plugs to use on a '67 273 V8 4bbl commando engine?

Ever thought about a stock plug? OH wait, the superceaded number for the stock plug?

I like Champs. Others curse'em. Champs were stock equipment.

Spark plugs? The most over-hyped performance upgrade ever?

LOL Stock work great!

Ahhhh...I guess stock it is.

The engine would have to be a preety hot street runner to start thinking about a cooler plug.
A different style plug is worth a shot, but it's your call.

I'm not a fan of Auto Lites myself, other swaer by them.

Trick plugs never showed me much. Though platinum plug has done well in my old chevy. MSD doesn't like Platinum plugs.

I run Denso plugs and have not had any issues with them in my Duster.

I used to like Autolites until their production was moved to China and quality went in the dumper. It took losing two catalytic converters on two cars before I got it thru my thick skull that Champions are junk. Get a Champion and an application-equivalent NGK, hold one in each hand and compare them just physically; the difference in quality is plain to see. I have never had a problem with NGKs, but if I couldn't get them I'd use Densos.
